Not sure if we're ever going to want to have more than one of these at
the same time, but these global variables are a code smell nonetheless.
I'm also deleting the existing member variables because they were
unused.
This was causing deadlocks when a game didn't load (including if RetroAchievements does not yet support it) because it was attempting to close the queue the the callback was currently running on, forcing LoadGameCallback to wait for LoadGameCallback to finish. However, it appears that recent changes to the queue have independently resolved the reason CloseGame was being called here in the first place.
Fix the UI hanging for several seconds when opening the Controllers
window.
Move the scan for Bluetooth adapters onto a separate thread so the Host
thread doesn't have to wait for it.
Only automatically scan for adapters once, when opening the Controllers
window for the first time. Add a Refresh button to let the user refresh
the adapter list afterward.
If you already have a mapping set in the advanced mapping dialog and
want to change it, the easiest way to do it is to press Clear and then
select the new mapping from the list. But pressing Clear causes the
dialog to close, forcing you to open it again, which is inconvenient.
This commit makes it so the Clear button doesn't close the dialog.
This feature allows overriding the frequency of the Vertical Blank Interrupt. For many games, this means that their gameplay speed will change without affecting audio, which would be useful by itself (e.g. grinding in RPGs).
However, there are games that use delta time for their game logic, which allows them to be played at >60 FPS at the same gameplay speed!
Some games aren't dynamic though, and require a patch to adjust their game speed variable.
On real hardware, stswi and stswx don't trigger any of the special
behavior for uncached unaligned writes that was implemented in 543ed8a.
This is confirmed by a hwtest (a new commit in
https://github.com/dolphin-emu/hwtests/pull/42).
This change fixes Dolphin's stswi and stswx implementations so they stop
triggering the special behavior, bringing them back to the behavior they
had before 543ed8a. No games are known to be affected, but Extrems has
reported that it affects homebrew they've made.
